The radial wires may be provided with strengthening rings if desired.
The prior art teaches the use of direct current powered air moving devices, portable electric fans, and directing and deflecting of air streams from air movers, but does not teach the use of an enclosed, wheeled, air mover with AC current operation and rechargeable battery operated power supply. The present invention fulfills these needs and provides further related advantages as described in the following summary.
The present invention teaches certain benefits in construction and use which give rise to the objectives described below.
The present invention is a portable air moving apparatus for providing personal air cooling and includes a container with open top and supported by plural wheels attached under the container. The container encloses electrical components including a battery, a radial flow air moving device, and a switch. These components are interconnected by electrical conductors such that the switch can make and break a circuit for driving the air moving device with the battery. A removable container lid provides an aperture for receiving an air exhaust from the air moving device which is then directed toward an individual to provide cooling. The container lid is adapted for being set to allow air flow into the container so as to feed the air moving device. The invention is particularly useful at the pool and may be safely used on the pool deck.
A primary objective of the present invention is to provide an apparatus and method of use of such apparatus that provides advantages not taught by the prior art.
Another objective is to provide such an invention capable of being easily moved from place to place.
A further objective is to provide such an invention capable of operating for an extended period before being recharges.
A still further objective is to provide such an invention capable of providing portable power to generally power inaccessible areas.
A yet further objective is to provide a powered, air handling apparatus that is safe to use around a swimming pool.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
The accompanying drawings illustrate the present invention. In such drawings:
FIG. 1 is an exploded perspective view of the preferred embodiment of the invention;
FIG. 2 is a perspective cutaway view thereof as assembled;
FIG. 3 is a perspective view thereof in typical operation;
FIG. 4 is perspective view thereof shown being moved; and
FIG. 5 is a partial perspective view thereof showing utility outlets of the invention.
The above described drawing figures illustrate the invention in at least one of its preferred embodiments, which is further defined in detail in the following description.
The invention is a portable air moving apparatus for providing personal air cooling. It comprises a container 10, with open top 12 and is supported by plural wheels 20 attached to the bottom of the container 10. The container 10 encloses electric components including: battery 30, an air-moving device 40 preferably of the radial flow type, as shown in FIG. 1, and a switch 50. The components are interconnected by electrical conductors 60, i.e., insulated copper wires, such that the switch 50 is enabled for making and breaking a circuit, as best seen in FIG. 1, for driving the air moving device 40 with the battery 30. A removable container lid 70 provides an aperture 72 for receiving an air exhaust 42 from the air-moving device 40. The container lid 70 is positionable for enabling an air flow into the container 10. This adaptation is accomplished using propping spacers 74, as shown in FIG. 3. One end 70′ of the lid 70 is propped open by spacers 74 so that air may flow into the container 10 between the one end 70′ and a ridge 14 extending upwardly around the open top 12. The lid 70 is maintained in the propped open attitude by resting an opposing end 70″ against the ridge 14 for support.
Preferably, the air moving device 40 protrudes upwardly through the aperture 72 of the container lid 70 as shown in FIG. 3 so that the air exhaust 42 may be directed beneficially while the appearance of the invention is not degraded, and the noise produced by the air moving device 40 is contained.
Preferably, the circuit further comprises an electrical outlet 65 mounted on the container 10 and accessible from its exterior as shown in FIG. 5. This outlet 65 may power an air pump to inflate water toys, drive an external fan, a misting device or any number of other power driven items normally used at poolside.
Preferably, the apparatus further comprises a handle 80 which is of such extent and position as to enable the movement of the container 10 by a standing individual, as shown in FIG. 4.
The circuit may further comprise a recharging device 90 of any standard type for replenishing depleted charge in the battery 30, and is interconnected for such service as shown in FIG. 1. Such devices are well known and typically draw current from an AC socket while converting such current to a DC type by first stepping the voltage down from 115 volts to about 12 volts AC and then rectifying this AC voltage to a DC voltage through a rectifying circuit. This is well known in the art and therefore will not be further defined or shown in the present description and drawings.
The container 10 is preferably made of a sound insulation material such as polystyrene or an equivalent material so that the noise of the air moving device 40 is muffled.
While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
